Figure 15: Peak Detection
Term interpretation
Collecting mode: The oscilloscope transforms the collected analog data into a digital form after
they are gathered in the following three different modes, that is, sampling, peak value detection
and averaging values.
Sampling: The oscilloscope takes samples from the signal at a equal time interval to reconstruct
the waveform in this mode, by which the analog signal can be expressed correctly in most cases,
yet, the rapid changes can not be collected between two sampling time intervals, causing the
confusion and loss the narrow pulse in the signal probably.
Peak value detection: The oscilloscope takes samples from the maximum and minimum of
signals in each sampling interval and shows the waveform with the sampled data in this mode,
thus, by which the oscilloscope may collect the possibly lost narrow pulse in the sampling mode
but the noise is obvious.
Averaging values: the oscilloscope collects several waveforms and average over them, and
displays the averaged waveform in this mode, by which the random noise can be reduced.
Duration time: When a new waveform is displayed, the previous waveform shown on the screen
does not disappear immediately only to be displayed for a period of time, that is, the duration time,
by setting which, the waveform can be displayed more continuously and thus a display similar to
that shown by the analog oscilloscope can be achieved.
Roll scan mode: The oscilloscope updates the waveform sampling points by scrolling display
through a screen from left to right in this mode, which is only applicable to the primary time base
setting of above 50ms.

correctly, the trigger can turn an unstable display into a significant waveform.
When starting the acquisition of data, the oscilloscope collects sufficient data to draw the
waveform at the left side of the triggering point. With waiting for the triggering condition, the
oscilloscope is gathering data continuously. After a trigger is detected, the oscilloscope gathers
enough data continuously to draw the waveform at the right side of the triggering point.
To make a trigger mode setting, do the following:
1.
Press the MENU key and the function menu appears at the right of the screen.
2.
Press the MENU ▲ or MENU ▼ key to select TRIG MODE and five options are displayed
at the bottom of the screen.

7.5 Triggering Control
There are three triggering modes including Edge triggering, Video triggering and Alternating
triggering. Each trigger mode is set by different function menu.
Edge triggering: The edge trigger type triggers on the incoming signal edge. Use the edge trigger
for all signals except for video related ones.
Video triggering: Perform video field trigger or line trigger on the standard video signals.
Alternate trigger: When the signal frequency different in Channel 1 and 2, it can also guarantee
the stability approaching in two channels.
The following describes the Edge triggering, Video triggering and Alternating triggering menus
respectively.
7.5.1 Edge Triggering
The Edge triggering is a mode by which trigger occurs at the triggering threshold value of the
input signal edge. With the Edge triggering selected, the trigger happens on the rise or fall edge
of the input signal, shown as the figure 37.

Trigger modes: There are three kinds of trigger modes available for this oscilloscope, they are,
４４
HDS2062M-N Handheld DSO & DMM
7-Advanced Function of Oscilloscope
Auto (acquires signal continuously), Normal (acquires signal when trigger conditions are met) and
Single (manually triggers the signal).
Automatic trigger mode: The oscilloscope can acquire the waveform without any triggering
condition detected in this mode, in which it will be triggered compulsively when waiting for a
specified period of time without any triggering condition ignited. When an invalid trigger is
enforced，the oscilloscope can not keep the waveform in phase.
Normal trigger mode: In this mode, the oscilloscope cannot acquire the waveform till it is
triggered. When there is not any trigger, the oscilloscope will display the original waveform
without new waveforms captured.
Single mode: In this mode, the oscilloscope will detect a trigger and capture a waveform at each
time when the customer presses the RUN/STOP key.
7.6 Selecting the acquisition mode
The Acquiring Mode menu is described in the list shown as below.
Function menu
Settings
Description
Sample
The waveform data is sampled at an equal time interval. The
sample mode accurately reconstructs the waveform, but cannot
respond to rapid changes and sudden peaks.
Peak Detect
The maximum and minimum data in the sampling interval are
picked up. The peak detect mode captures rapid changes and
sudden peaks, but the waveform becomes noisy.
Average
Multiple samples are averaged together. The average mode
reduces the noise level, but the waveform must be repetitive.

9.2 Appendix B: Maintenance and Cleaning
9.2.1 Maintenance
Do not store or place the instrument in locations where the liquid crystal display (LCD) may be
directly exposed to the sunshine for a long time.
Be careful: Do not spray liquid into the instrument.
Cleaning
Inspect the instrument and the probe frequently in accordance with operating conditions. Clean the
outer surface of the instrument according to the following steps:
1. Wipe off the floating dust outside of the instrument and the probe by using soft cloth.
When cleaning the LCD, do not scuff the transparent LCD protective screen.
2. Wipe the instrument in power off status by soft cloth that is moist but not dripping. It is
allowed to be cleaned by soft detergent or fresh water. Do not use any abrasive chemical
detergent to avoid the instrument or the probe being damaged.
Warning: Before running, please confirm that the instrument has been dried out so as to
avoid electrical short circuit and personal injury caused by moisture.
9.2.2 Storage of Oscilloscope
If the test tool is to be stored for a long time, it is required to charge the lithium battery before
storage.

Charging the oscilloscope
The lithium battery is possibly not charged when delivery. To make the battery with enough
electric quantity, it must be charged for 4 hours (the test tool must be turned off during charging).
The battery can supply power for 4 hours after being charged completely.
When supplying power by using the battery, a battery indicator is displayed on the top of the
screen to show the consumption condition of electric quantity. The symbols that are possibly
and , where
shows that the battery can only be used for about 5
appear include , ,
minutes. To charge the battery and power the instrument, connect the oscilloscope using a power
adapter according to Figure 1 to charge the battery. The charging speed can be increased by
turning off the test tool.
Notice
To avoid superheat of battery during charging, the environment temperature is not allowed to
exceed the permissible value given in technical specification.
Note:
No hazard will occur even connecting the charger for a long time, e.g. during a whole weekend.
The instrument can automatically switch to slowly charging status.
9.2.3 Replacing the Lithium Battery Unit
It is usually not required to replace the battery unit. But when it is required to replace it, only
qualified personnel can carry out this operation, and only use the same specification lithium
battery.
